RE: Comparison to Avacta19 Aug 2020 17:17
The main difference between odx & avct is that odx is an antibody test & avct is an antigen test. Antibodies show you've had the virus & can take 2 weeks for the body to produce testable amounts whereas antigen tests show whether you have the virus right now & can detect the virus even before the body has even started producing antibodies.
